El amandla kazibuthe yoMhlaba yenye yezinto eziphambili ezivumela ukuhlala kweplanethi yethu. Iyasikhusela kumasuntswana ahlawuliweyo kunye nemitha evela kwi umoya welanga. Eli khaka lenziwa enkosi kwi iintshukumo ezikhawulezayo zezixa ezikhulu zentsimbi engamanzi kumbindi ongaphandle weplanethi. Ngokwemveli, izazinzulu zazikholelwa ukuba umbindi woMhlaba uphulukene nobushushu obuninzi, obumalunga nama-3000 degrees, kule minyaka iyi-4,3 yeebhiliyoni ezidlulileyo ukugcina le magnethi.
Uphando lwakutsha nje, nangona kunjalo, lucebisa ukuba oku kupholisa ayisiyiyo yodwa inkcazo yokuziphatha kombindi woMhlaba. Kulapho ke luna kwindawo. Ixesha elide, impembelelo yayo yayingahoywa, kodwa ukusebenzisana komxhuzulane phakathi koMhlaba neNyanga ngoku kukholelwa ukuba kudlale indima ebalulekileyo kwi-geodynamics yomhlaba, evumela umbindi woMhlaba ukuba uhlale usebenza ngokwaneleyo ukugcina intsimi.
Imodeli yeklasiki yomhlaba wemagnethi yomhlaba
Ngokwemodeli yakudala, umbindi woMhlaba uye waphola kancinci kancinci kwibhiliyoni yeminyaka ukugcina imagnethi isebenza. Nangona kunjalo, uphando olutsha kwi-geochemistry kunye nemodeli lubonisa ukungahambelani. Izifundo ziyaqhubeka i-basalts kunye ne-carbonates Uphononongo lwamandulo lubonise ukuba ezi zixhobo azizange zibe phantsi kobushushu obugqithisileyo obucatshangelwayo ekuqaleni.
Olu lwazi lukhokelele ukuba oosonzululwazi bacinge ngokutsha ngokupholisa okungundoqo, becebisa ukuba undoqo woMhlaba uphulukene needigri ezimalunga nama-300 kuphela, kunokuba kuqikelelwe ukuba zingama-3000 degrees, kwiminyaka eyi-4,3 yeebhiliyoni ezidlulileyo. Lo mahluko ubalulekileyo ubalelwa kwi impembelelo yomxhuzulane yeNyanga, edlale indima ebalulekileyo kuzinzo kunye nokusebenza kwegeodynamics.
Impembelelo yeNyanga eMhlabeni
La umxhuzulane wenyanga Ayichaphazeli kuphela iilwandle zomhlaba, ivelisa amaza, kodwa inefuthe elithe ngqo kulwandle. isambatho somhlaba. La mandla amaza abangela ukuguqulwa okuncinci okufikelele kumbindi wangaphandle, ovuselela ukuhamba kwe intsimbi engamanzi ngaphakathi embindini. Ezi ntshukumo zivumela amandla aneleyo ukuba aveliswe ukugcina umhlaba wemagnethi.
Ukongeza, i ukujikeleza komhlaba kunye nokuthambekela kwe-axis yayo kunempembelelo kwintsebenziswano neNyanga. Ukuthambekela okuncinci kwe-axis kunye ne-polar flattening kubangela i-oscillations ethi, xa idityaniswe namandla omxhuzulane weNyanga, ivelise ukuguquguquka kwamaxesha athile kumbindi woMhlaba, okuguqulela kwiipulses zeNyanga. calor kunye nentshukumo eqhubekayo yentsimbi engamanzi.
I-geodynamics engazinzanga kunye nendima ye-Earth-Moon system
La ukungazinzi kwe-orbital yeNyanga kunye nezitenxo ekujikelezweni koMhlaba zizinto ezibalulekileyo ezenza umahluko kumandla olwandle ngexesha lejoloji. Iziphumo ezidibeneyo zolu tshintsho zibangela ukuguquguquka kwi-geodynamics Umhlaba, onokuthi ekugqibeleni uvelise i-spikes kumsebenzi wentaba-mlilo kunye nezinye iziganeko ezibalulekileyo zejoloji, ezifana nogqabhuko-dubulo olukhulu lwentaba-mlilo.
Ezi ziphumo zamaza zinamandla ngokwaneleyo ukuvelisa imithambo yobushushu ukusuka kumbindi woMhlaba, nto leyo enokuphembelela iitectonics zepleyiti kunye nokuhanjiswa kobushushu kumaleko aphezulu eplanethi. Impembelelo yomxhuzulane yeNyanga ayigcinanga nje undoqo woMhlaba usebenza, kodwa ibe yinto emiselayo kwinguquko yentaba-mlilo.
Ukuthelekisa nezinye izidumbu kwisixokelelwano selanga
Impembelelo yomxhuzulane phakathi kweenyanga kunye neeplanethi azikho kuphela kuMhlaba kunye nesathelayithi yawo yendalo. Kwinkqubo yelanga, eminye imizekelo ephawulekayo ibandakanya Io, enye yeenyanga zeJupiter, efumana umsebenzi omkhulu wentaba-mlilo ngenxa yamandla amaza abangelwa kukudibana kwawo nesigebenga segesi. Ezi mpembelelo azichaphazeli nje kuphela i-Io's geodynamic behaviour, kodwa zikwaphembelela umsebenzi we-volcanic.
Olunye uphando lucebisa ukuba exoplanets ezifana noMhlaba, ezikwezinye iinkqubo zeenkwenkwezi, zikwabonisa iindawo zemagneti ezomeleleyo ngenxa yonxibelelwano olufanayo neenyanga okanye iiplanethi ezingabamelwane. La mandla ongezelelweyo, avela ekusebenzisaneni komxhuzulane, anokuba ngundoqo ekuqondeni ukuba imimandla yamagnetic kunye nokuhlala kweplanethi kugcinwa njani kwamanye amazwe.
Impembelelo yemagnethi yenyanga kuMhlaba wokuqala
Kuye kwafunyaniswa ukuba ebutsheni bakhe, i luna Ikwanayo nemagnethi yayo, eyenziwe ngumbindi wentsimbi. Lo mmandla wamagnetic wenyanga wawunokubakho yomelele kakhulu njengalowo woMhlaba, kwaye impembelelo yawo yayinokuba yinto ebalulekileyo kwiminyaka eyibhiliyoni yokuqala yeplanethi yethu.
Ngeli xesha, i Sol Yayisebenza ngakumbi kwaye ikhupha amadangatye elanga ahlasele umhlaba. INyanga, enemagnethi yayo, yasebenza njenge ikhaka elikhuselayo ezongezelelweyo, ukunceda Umhlaba ukugcina umoya wayo kunye nokukhusela ekulahlekeni kweegesi ezibalulekileyo ezifana nenitrogen kunye neoksijini. Le nyaniso yayinokuba sigqibo kuphuhliso lweemeko eziyimfuneko ebomini.
Njengoko Inyanga yaphola yaza yaphulukana nemagnethi yayo, ukukwazi ukukhusela uMhlaba kwancitshiswa, kodwa impembelelo yayo yomxhuzulane iye yaqhubeka ifaka amandla kumbindi woMhlaba, oye wabaluleka ekuqhubekeni kwentsimi yamagnetic yomhlaba kude kube namhlanje.
Namhlanje, nangona iNyanga ingenawo umhlaba wemagnethi, ukusebenzisana kwayo rhoqo kunye noMhlaba kuhlala kubaluleke kakhulu kuzinzo lwe-geodynamics yeplanethi kunye nokugcinwa kwemagnethi esikhusela kumoya welanga.
Unxibelelwano phakathi kweNyanga noMhlaba lube sisiseko senguquko yeatmosfera yethu kunye nokukhuselwa kweplanethi yethu. Nangona iNyanga ingumzimba ongasebenziyo ngokwejoloji namhlanje, impembelelo yayo yangaphambili ibibalulekile kuzinzo loMhlaba kumanqanaba awo okuqala kwaye iyaqhubeka nokudlala indima ebalulekileyo kutshintsho lwejoloji kunye nokuveliswa kwemagnethi.
